To all who-m, ilmu concern:

Be it. known that we, Gas'rox PAUL JEAN LIQX and At'ocs'ra .ll1 'ce:\r: Bmuafi, eitizens of the Republic of France, residing, respectively,at Levallois-Perret, Seine, F rane'e, and Paris, France, have invented Improvements in Carburetors, of which the follow: 'ing a specification.

This invention relates to charge forming devices for internal combustion engines and has for its object to provide means whereby the heat of the exhaust gases is utilized to increase or facilitate the volat-ilization and \"aporiiation of? the fuel, particularly hydrocarbons which are solid or but slightly volatiles Such means embody heating apparatus comprising a chamber adapted to forum-a collector of the exhaust gases from the motor and an extension, shuntor branch of which is arranged to form a hearth for the fusion and vaporization of the hydrocarhon; and an adjoining chamber one wall of we 1: at least also constitutes a wall-of the first mentioned or collecting chamber, this second chamber serving for the supply, circulation and heatingofthe air utilized for the formation of the explosive mixture.

' A practical form of apparatus;embodying 'this invention is illustrated by way of examplegin the' accompanying drawingsiin its application to the utilization of a solid hydrocarbon such as naphthalene. I

Figure l is a vertical section of the heater and of the parts contained therein, the section corresponding partly to the lines A A of Figs. Sand -1 and partly t-othe line l'-l of Figlfi. Fig. Qis a longitudinal section corresponding to' the lines {loft Figs. 3 and 4 and D l) of Fig.5; Fig. 3 is a transverse section corresponding to the lipes section corresponding to the lines G 'tr of Figs l and 2; Fig; o ls a transverse section corresponding .to t-llezlllit'S lC--l; of Figs. 1

' and Fig. (i is a longitudinal section corn spending to the lines llIl of Figs. 3

--vlinders c of the motor as shown in Figs.

2, 3 and 4 of the drawings. Connected to a branch (1 of the chamber a is a pipee through which the gases after their utilization in the heaterescapc. Arranged in or upon a loop-like extension or shunt 1,2, 3, 4, 5, 6 of the chamber a, in a body a integral withthis extension, are the receiver 1 for the solid hydrocarbon, t-hedistributer g and the receiver II, for the fused combustible, and the atomizer i. Thereceiver f is so arranged that the solid hydrocarbon it contains shall be fused by the heat of the exhaust gases circulating through thelooplike extension 16. extension or shunt may, in some cases, open into the atmosphere or into a silencer, instead of back into the chamber a.

j is .the second chamber of the heater, the wall 7 of which is common with the first chamber a (Figs. 3 and The chamber serves for the supply, circulation and heat-- ing of all the air utilized for the formation of the explosiven ixture:

A branch inlet m is arranged as shown in Figs. 1, 1 and 6, for permitting the air which'has been charged with naphthalene vapor to enter the chamber 7'. This air is mixed with the naphthalene vapor in a con-' duit preferably heated by being located within or by contact with the two chambers a and This conduitcomprises a chamber 9 having an adjustable admission tit-ting 8 therein. see Figs. 2, 5 and 8, said chamber 9 preferably arranged adjacent the chambers and 5 of the extension or shunt ]6; and a curved pipe 10, 11, extending from the chamber 9 and' communicating with a pipe l9, 13, which is connected to the wall of the )l'ulltiltlllltl' m, and a wall of which branch inlet is preferably conunon with the chamber At the junction of the. pipes 10, 11 and 12,13 located the atomizer i, which is arranged to extend into the pipe 1.

A branch 10 is provided. as shown for in stance in Figs. 1 and 3, for the admission 1 f additional air. which may be allowed to enter through'a short pipe section 'li l'ltfiil lg tl'ierein an iutomatic. valve 1:"). For the heating of this additi nal air,- a downwardly directed and horizontally arranged partition or ballle 17, as shown in Figs. 1.4 andG is provided within the chamber j,.and fivhich deflects the pure air at first towardthe inlet branch in, where it mixes with the air already charged with naphthalene vapor and The branch 6 of the forms with it the mixture to be utilized in the motor. This mixture then passes between the upper face ofthe partition 17 and the upper. inside wall of the chamber j, and 5 then through the branch coupling 13, into a box or chamber 19, which is furnished with a throttling valve '20, as shown for instance in Fig. 4, and through the medium of which valve the mixture is admitted to the inlet 21 of the motor.

The branch inlet m serves as a seat for a rotary valve plug n, which according to the position given to it, allows air charged with naphthalene vaponto enter the chamber 7' from the pipe 13; or air charged with spirit such as petrol from the atomizer Is (for the a starting of the motor) to enter such cham bo l-jg; through the pipe 22. s e apparatus described works in the following manner :-The reservoir f being charged with naphthalene in lumps or crystals, and the plug n being in a position to en the branch 22, and close communica-' t on between the conduit 13 and the branch air inlet m the tlyudxeel' of the motor is worked by hand so as to produce in this branch an aspiration of' air charged with the volatile vapor of the petrolor the ,lilre. The motor then works by this volatileatapor for a time sufficient to allow the hot exhaust. gases-passi into the chamber a of the apparatus by he pbr'ts bJand following in part the circuit 1, 2, 3, 4, 5, '6 to heat the naphthalene reservoir fand the parts l1, When these parts are suliiciently heated the cock n is so turned as to close communication with thejbranch 22 and to open coinmunicatioh with the branch 13, in which position it isshown in Figs/'1 and 4. The-fused naphthalene asses through th perforations '0 and past he opening cock 9 into the liquid receptacle h which is provided with a float p.- W'hen the liquid attains the desired level in the receptacle h the raised float closes the supply orifice by a-valve q thereon. The liquid then passes from the receptacle luby the conduit 23 in which may be arranged, as shown, a ball 2: for regulatin the flow, into the "ertical p'asmge of 1; 1e atomizer and is drawn through the orifice or orifices s, Fig. 7, the delivery through which is regulated by the needle 1'. .This as jiration is caused by the air descending in e reverse direction in the pipe t1 and the current of which is divided by the-conical cap of the atomizer, at the same time being throttled between the lower edges of this latter and the walls of'the said pipejll while the lidiiid drawn in through the orifices s is atomized beneath the base of the cone and escapes by the openings t. The'mixture of'air and naphthalene vapor,

previously heated by contact with the'walls' -'of the circuit 8,, 9, 10, 11, passes thro'u h the B g-pipes 12 and 13 into thebranch in ct m,

through the perforations v in the plug n and diffuses in the, i are air which .is heated and admitted into't e apparatus by' the automatic valve 15 and the branch 16.

The apparatus described not only permits, as has been stated above, of a better utilizatio'n of the heat of the exhaust gases,-but also offers the following advantages :The exhaust gas collector and its extension or shunt form a hearth for the fusion of the naphthalene and at the same time a'heater for the pure air and-the carburetcd air. It can thus receive the cook 12, for distributin the mixture 'of naphthalene and air or 0%: the volatile vapor and air at will; and asingle automatic air entry valve, as well as a single thmttling valve, for bothmixtures of the apparatus-to be reducedtf at we claim is:-- I 1.
